Clarity & Durability

The Alpha & Delta D6 in-ear monitors were made with two goals in mind: First, a clear, balanced sound signature; and second, the kind of durability that allows you to enjoy it year after year. On both fronts, these IEMs deliver big time. Paired with a dual air chamber design licensed through HDSS (High Definition Sound Standard), the custom-tuned 10-millimeter dynamic drivers bring a spacious soundstage, reduced distortion, and ample detail. The silver-plated-copper cable ensures excellent signal transmission, and for maximum durability, it uses eight cores—double that of most earphone cables. To help the IEMs withstand daily use, there’s reinforced strain relief at the “Y” split and a spring-protected 3.5-millimeter jack. Finally, it’s all backed by Alpha & Delta’s 3-year warranty.

The Reviews Are In

One Head-Fi reviewer says, “With its mature tuning, the D6 is a more serious offering from A & D that aims more towards transparency and resolution compared to the D2’s fun and relaxed approach. The Alpha & Delta D6 impresses not only with its clarity and detail but also with soundstage and imaging. Anyone looking for something more balanced and less V-shaped than the typical offerings in the $100 range should take a look at the Alpha & Delta D6.”

I got my D6 earphones today. Right out of the gate they sounded pretty good. A bit bright but I'm letting them break in by playing a 'low dynamic' playlist on Tidal at low volume. Came back a few hours later and now they sound positively tinny... unplugged them and plugged in a pair of Sennheiser PX 100 - II and directly compared on a few songs. No comparison, the Senns are (so far) much better with a rich full sound. So... I'm really hoping that the D6s will improve. Update: They sound much better after about 36 hours of breaking in with a much fuller sound. Inner details are lacking a bit, so I'm hoping they continue to improve. I'll give them another day or two and then do another comparison to the Sennheisers for a final evaluation. Update II: Happily, all the prior negatives are gone ;-) These phones do have a breakin period and at 56 hours all doubt has been removed. They may even continue to improve but at this point they're entirely satisfying. Clean, neutral sound. A great budget set of earphones for those who like clear, transparent reproduction. I did directly compare them again to the Sennheisers and now the Sennheisers boost in the midbass is obvious. That bass emphasis is very attractive even for someone who's not a basshead. The problem is that the Senn's bass emphasis masks the other frequencies and for instance on Paul Simon's "You can call me Al" especially @ the bass solo @ 3:44 the Senns make it sound a bit distant and slightly muffled. Whereas the D6s render it much more clearly. Thumbs up for me.
